TeleTech Holdings

(TTEC) - Get Report

traded actively after the company forecast better-than-expected fourth-quarter sales. The outsourcing provider put its top line at roughly $300 million, topping analysts' forecast of $278.7 million. TeleTech said results were buoyed by government work related to hurricane relief efforts.
